Analytical Guard Cartridges, HxSil C8, PN: 79451 Details
Guard columns can provide many benefits when used upstream from an analytical, preparative, or semi-preparative column. Guard columns are typically chosen to have the same packing as the primary column. HxSil C8 is packed in a guard cartridge that can be conveniently replaced without disconnecting the cartridge holder from the main column. Any compounds or particulate material that would block the frits or highly adsorb to the primary column will do so on the guard column, thereby protecting and extending the lifetime of the more costly column. In addition to protective uses, guard columns can be used as sacrificial preparative components.
This pack comes with 5 replacement stainless steel cartridges.
